Problem: Consider the reaction:2 CH3OH(g) + 3 O2(g) → 2 CO2(g) + 4 H2O(g)Each of the molecular diagrams represents an initial mixture of the reactants.How many CO2 molecules form from the reaction mixture that produces the greatest amount of products?

FREE Expert Solution

2 CH3OH : 2 CO2

3 O2 : 2 CO2


a.

3 molecules CH3OH → 3 molecules CO2

3 molecules O2 → 2 molecules CO2 → limiting reactant


b.

1 molecule CH3OH → 1 molecule CO2 → limiting reactant

6 molecules O2 → 4 molecules O2

Problem Details
Consider the reaction:
2 CH3OH(g) + 3 O2(g) → 2 CO2(g) + 4 H2O(g)
Each of the molecular diagrams represents an initial mixture of the reactants.

Three space-filling molecular diagrams labeled a, b, and c. Diagram a is a collection of three molecules composed of a black and red sphere combined surrounded by four smaller white spheres (one on the red sphere and three on the black sphere), and three molecules composed of two red spheres combined. Diagram b is a collection of one molecule composed of a black and red sphere combined surrounded by four smaller white spheres (one on the red sphere and three on the black sphere), and six molecules composed of two red spheres combined. Diagram c is a collection of four molecules composed of a black and red sphere combined surrounded by four smaller white spheres (one on the red sphere and three on the black sphere), and two molecules composed of two red spheres combined.
